ROLLER BEARING.

To aZZwhom it may concern: 1

Be it known that 1, WILLIAM F. HUTHER, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new an useful Improvements in Roller Bearings, of whichthe following is a specification.

My invention relates to roller bearings.

An important object of theinvention is to provide a cage included in theroller bearing, which cage is formed from a single section of sheet orplate metal, and adapted for receiving and holding the rollers or rollerelements in the proper assembled condition, and preventing them frombeing displaced with respect to the longitudinal axis of the bearing,and also from crowding.

A further object of the invention is to provide a cage of the abovementioned character, which is simple in construction, cheap tomanufacture, strong and durable.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification, andin which like numerals are employed to designate like parts throughoutthe same.

Figure 1 is a central longitudinal section through a roller bearingembodying my in vention, parts being broken away,

Figure 2 is a similar view showing the roller in section,

Figure 3 is a plan view of the cage, parts broken away and parts insection,

Figure 4c is a longitudinal section taken on line 1-4 of Figure 3, and,

Figure 5 is a transverse section through a slightly different form ofroller and cage embodying the invention, and correspondmg with theposition shown in Fig. 1.

In the drawings, wherein for the purpose of illustration are shownpreferred embodiments of my invention, the numeral 5 designates an innerbearing member, preferably havin an outer tapered surface 6. Surroundlngthis inner member is an outer bearin member 7, preferably having atapered or conical inner surface 8, as shown. The surfaces 6 and 8preferably form a tapered annular passage or space.

The numeral 9 desi nates my improved cage, as a whole,.whic may beformed of sheet or plate metal, such as steel. This cage may be astamping and embodies an Specification of Letters Patent.

annular body portion 11, flat incross section, and arranged diagonallyof the tapered passage. The body portion 11 is provided withequi-distantly, spaced openings 12, which are tapered, for receivingtapered rollers 13. It is obvious that any other form of rolling elementmay be employed. The rollers 13 are confined between the surfaces 6 and8, to contact therewith.

Formed integral with the opposite edges of the body portion 11 areannular flanges 14 and 15, preferably bent from the material of thesame. These flanges extend in opposite directions with relation to thediagonal body portion 11. The flanges 14 and 15 have pivot elements 16,which are preferably hollow and tapered, the same extend-- ing inwardlyto the pivotally mounted within tapered recesses 17, formed in the endsof the rollers 13. The pivot elements 16 are in the form of trunnions,which are pressed or spun from the material of the flanges 14 and 15,which operation may be performed after the rollers 13 are assembledwithin the openings 12, if desired.

In Figure 5, the cage 9 has its flanges 14 and 15 provided with openings18, instead of the trunnions 16. The rollers 13 are provided withtrunnions 19, pivoted within the openings 18.

The tapered arrangement of the surfaces 6 and 8 and the tapered rollers13, serves to take up the end thrust or load, as well as the radialthrust, and provides for an adjustment of the bearing, to take up allslack due to wear. The cage is preferably constructed of sheet steelhaving a suitable thickness whereb it is rigid.

It is to be un erstood that the forms of -my invention herewith shownand described member having a frusto-conical.outer surface unobstructedat its larger end, an outer race member having an inner frusto-conicalsurface spaced away from the outer surface of the inner member toprovide an annular passage tapering longitudinally in one diflange,tapered rollers arranged in said passage between said flanges anddecreasing in diameter toward the reduced end of the passage, saidrollers having recessed ends, and trunnions integral with same flangesand extending into said recesses.

In testimony whereof I aflix my signature.

WILLIAM ,F. HUTHER.
